What else can I help you with?
When the core of a star shrinks after hydrogen fusion stops the core heats up but what happens to the star?
The rest of the star expands.
What happens to air as a stove heats it?
The air expands as it is heated this is due to the increased activity of the molecules composing the air. It also rises as its density is reduced compared to the cooler air in the room. The pressure of the warm air remains the same as that of the cooler air.
When a balloon heats up and expands is it thermal energy?
When any state of matter is heated it expands.
What happens to an object's density when it heats up?
When an object heats up, its density typically decreases. This is because as the object's temperature increases, its particles gain energy and move more quickly, causing the object to expand. As a result, the same amount of mass now occupies a larger volume, leading to a decrease in density.
Do the tiny particles in boiling water mover closer together?
Yes, the particles in boiling water move further apart as the water heats up and expands. This leads to a decrease in density and an increase in volume of the water.
What does water become less of when it heats?
if you are talking about what form it is it, it becomes less of a liquid and more of a gas (: It becomes less "dense" eventually turning into a gas, as above has stated.
Why might the air inside a balloon expand in he sun?
Because when air heats up it expands.
What does the sun have to do with the wind?
its the energy source. Sun heats Earth, Earth heats air, air expands, air rises, new air blows in. Its called wind.
What happens to the density of the air as air on the surface of the earth warms?
The sun heats the surface of the Earth, and some of this heat goes into warming the air near the surface.
What type of thermal energy is When a hair dryer heats a balloon and the air inside it the balloon expands?
conduction
Why after the hot water in the kitchen heats up the pressure goes out and trickles the hot water?
As the water heats up the washer in the tap, it expands. This causes the washer to partially block the open valve.
Why does your truck die when you hold the gas down for to long?
it dies because the metal heats up and expands and then eventually it will jam.
